I think that's not PR show. For me it looks that Trump really want to end his war and get Nobel Peace Prize for it. But some of his statements looks that he is living in alternative reality.
I wish that this meeting would give results, it's time to end this war. But I'm afraid that again it will end without any result. First because fate of Ukraine can't be decided without Ukraine. And also because it looks that Putin isn't ready to make any discounts on their requirements.
I don’t think these talks will lead to anything. Trump just wants that Peace Prize for his own ego, not real change. Russians won’t stop at what they’ve taken — they’ll just regroup and start again. It’s hard to negotiate with them when they’ve got little left to lose.
